Question

A 2000 N net force will give a car with some amount of mass an acceleration of 4 m/s2

Answer 1

Answer:

2m/s²

Explanation:

Given parameters:

Net force on the car  = 2000N

Acceleration = 4m/s²

Unknown:

Acceleration of a car twice the mass  = ?

Solution:

Let us first find the mass of the car;

 Force  = mass x acceleration

         Mass = $\frac{Force }{acceleration}$  

 Mass = $\frac{2000}{4}$   = 500kg

 Now,

     whose mass is twice that of the car

    Mass of the new car = 2 x 500  = 1000kg

So;

  Acceleration  = $\frac{Net force }{mass}$  

  Acceleration  = $\frac{2000}{1000}$  = 2m/s²
